We analyzed antigen-binding residues from the variable domains of anti-CD4 antibody 13B8.2 using the Spot method of parallel peptide synthesis. Sixteen amino acids, defined as Spot critical residues (SCR), were identified on the basis of a 50% decrease in CD4 binding to alanine analogs of reactive peptides. Recombinant Fab 13B8.2 mutants were constructed with alanine residues in place of each o...
Contemporary factories in capital intensive industries such as semiconductor manufacturing are very complex, with many sources of risk. The highly competitive and global business environment forces companies to analyze, design, and continuously re-design factories with distributed multidisciplinary teams. Traditional factory design approaches using spreadsheets and stand-alone simulations canno...
The interference of antibodies to factor VIII coagulant protein (Vlll:C) of 9 nonhemophilic patients with the binding to factor VIII coagulant antigen (VIII:CAg) of a reference hemophilic ‘251-Fab’ reagent, used in a liquid phase Vlll:CAg assay, was studied. The binding competition was estimated from immunoradiometric assay (IRMA) doseresponse slope of Vlll:CAg present in patient plasma. interf...
The interference of antibodies to factor VIII coagulant protein (VIII:C) of 9 nonhemophilic patients with the binding to factor VIII coagulant antigen (VIII:CAg) of a reference hemophilic 125I-Fab' reagent, used in a liquid phase VIII:CAg assay, was studied. The binding competition was estimated from immunoradiometric assay (IRMA) dose-response slope of VIII:CAg present in patient plasma, inter...
Treatment of porcine immunoglobulin M (IgM) with pepsin at pH 4.6 and 37 degrees C was found to gradually remove Fab arms and Cmicro2 domains over a period of 18h. Structural studies failed to find any other change. The main products can therefore be regarded as IgM-like molecules with limited numbers of Fab arms and Cmicro2 domains. Results indicated that this removal of Fab arms is probably a...
33 patients with advanced malignant melanoma were studied after intravenous administration of 131I-labeled Fab fragments specific for p97, an oncofetal glycoprotein of human melanoma. In all, 47 gamma camera imaging studies were performed for the purpose of localization of metastatic deposits. In addition to tumor, 131I-Fab uptake was also seen in liver and kidney. 20 of these studies included ...
The Fab-7 boundary functions to ensure the autonomous activity of the iab-6 and iab-7 cis-regulatory domains in the Drosophila Bithorax Complex from early embryogenesis through to the adult stage. Although Fab-7 is required only for the proper development of a single posterior parasegment, it is active in all tissues and stages of development that have been examined. In this respect, Fab-7 rese...
Using the mouse passive transfer model, the effects of purified human myasthenic immunoglobulin G and of the monovalent Fab fragment on neuromuscular junctions were investigated. Treatment with IgG markedly reduced amplitudes of miniature endplate potentials. When Fab fragments were transferred alone or with subsequent addition of IgG no neuromuscular transmission block was induced. Myasthentic...
X-ray analysis at 3.2-A resolution revealed that the Mcg IgG1 (lambda chain) immunoglobulin is a compact T-shaped molecule. Because of the hinge deletion, the Fc fragment lobe is pulled tightly upward into the junction of the Fab arms. Along the molecular twofold axis, the Fab arms are joined by an interchain disulfide bond between the two light chains. The antigen combining sites consist of la...
Abstract With the advancement of genetic engineering, monoclonal antibodies (mAbs) have made far-reaching progress in treatment various human diseases. However, due to high cost production, increasing demands for antibody-based therapies not been fully met. Currently, mAb-derived alternatives, such as antigen-binding fragments (Fab), single-chain variable fragments, bispecifics, nanobodies, and...
